CRUDE-OIL BURNER.

Specification of Letters Patent.

Patented Feb. 15, 1910.

Application filed January 10, 1910. Serial No. 537,098.

To all whom it may concern:

Be it known that I, FREDERICK D. STAL- roRD, citizen of the UnitedStates, residing at Frederick, in the county of Tillman and State ofOklahoma, have invented certain new and useful Improvements in Crude-OilBurners, of which the following is a specification.

This invention comprehends certain new and useful improvements inburners for crude oil or other hydrocarbons, and the invention has forits object a simple, durable and eflicient construction of device ofthis character which may be easily applied to the fire-pot of a cookingor heating stove of any ordinary or conventional type, with a minimum oflabor, and which, when in use, will effectively heat the stove andspread the heated products of combustion to the best possible advantage.

With this and other objects in view as will more fully appear as thedescription proceeds, the invention consists in certain constructions,arrangements and combinations of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in which:

Figure l is a perspective View illustrating one application of mydevice; Fig. 2 is a longitudinal sectional view of the fire-pot of astove and of the crude oil burner mount ed therein; Fig. 3 is atransverse sectional view on the line 33 of Fig. 2; and, Fig. 4 is adetail sectional view of a sight feed which may be employed.

Corresponding and like parts are referred to in the followingdescription and indicated. in all the views of the drawings by the samereference characters.

In the present instance I have shown my invention as applied to akitchen range or cooking stove, designated A, although it is to beunderstood that the invention is not limited to this use, but is equallyadaptable for heating stoves with fire-pots of difierent shape, it beingonly necessary to change the shape of my device accordingly.

Mounted in the fire-pot 1 of the stove A is a trough or casing 2, whichis open at its top, as shown, and which in the present instance isrectangular in shape so as to con- The bottom 3 of the casing 2 restsdirectly upon the grate 4, although it may be supported in the fire-potin other ways. The casing 3 is designed to contain any desired number ofoil receptacles 5, there being two in the present embodiment of theinvention. These oil receptacles 5 are formed with any desired number oftroughs 6 separated by longitudinal webs 7, thereceptacles beingdesigned to rest loosely upon the bottom 3 of the casing 2 and to beturned by tilting them on either edge, whenever it is desired to presenta fresh trough or pocket upwardly to receive the fuel to be burned.

In order to assist in the tilting operation, the casing 52 is providedwith lugs 8 which project upwardly from the bottom of the casing, saidlugs serving as stops. It will thus be understood that in order to turnor tilt any of the receptacles 5, it is only necessary to remove a lidof the stove and apply a poker or lid lifter or any other instrument,and push or slide the receptacle in one direc tion or the other intoengagement with one of the lugs 8, whereupon by pressing downwardly uponone edge of the receptacle, at an oblique angle, the receptacle may betilted and then slid back to its position underneath the drip nozzle 9.As there are two receptacles 5 in the present instance, there are twodrip nozzles, said nozzles being connected to an oil supply pipe 10which may be entered in the stove in any desired way underneath thegrate, as through the lower draft door 11, said door being utilized inthe present embodiment of the invention to control the draft and admitair so that it may enter and pass up through the grate 4 into a centralopening 12, with which the casing 2 is formed. The supply of oil may bese cured from a tank 13 or the like secured to the wall of the room inwhich the device is located or supported in any other manner, and thesupply pipe'lO may be provided in its length with a sight feed which inthe present instance embodies a glass cylinder 14. A drip nozzle 15enters the upper end of the glass cylinder 14 and above said nozzlethere is a globe valve 16 so that the quantity of oil passing throughthe nozzle may be controlled. Manifestly, by the use of this sight feeddevice, it may be readily determined how much oil is passing through theburner, without the necessity of removing any of the lids of the stoveor of otherwise obtaining direct access to the stove for this purpose.The opening 12 which is overflow of oil from doing any damage bydripping down through the bars of the grate at. The collar 17 alsoserves the function of a support for a sleeve 18 which is adapted to heslipped downwardly therein and which a is held removable by frictionalengagement in the collar. This sleeve 18 is formed preferably integrallywith a hood or cap piece 19 which extends over the nozzle pipes 9 andover the central opening 12 and which is provided with a downwardlyextending marginal edge 20, said hood serving as a spreader for the airas it flows up through the opening-l2, properly directing the air intothe troughs or pockets 6 of the oil receptacles 5. The sleeve 18 isformed at its upper end with lugs 21 by which it serves to directlysupport the nozzle pipes 9. If desired, the casing 2 may be providedwith up- 7 right partitions 23 spaced from the vertical walls of thecasing, so that water may be poured into the spaces between thepartitions and the adjacent casing walls to tend to prevent theformation and accumulation of soot.

From the foregoing description in connection with the accompanyingdrawing, the operation of my improved crude oil burner will be apparent.In the practical use of the device, the oil controlled by the globevalve or cock 16 will pass down the supply pipe 10 and up into thenozzle pipes 9 and will finally issue from the tips of the nozzles anddrop into the upwardly facing troughs of the receptacles 5, directlyunderneath said nozzles. The air will be spread out over these pocketsby passing in through the lower draft door 11 of the stove and thenceupwardly through the grate bars a into and through the opening 12, andwill be spread effectively by the cap piece or spreader 19,

casing being provided with stop lugs against 7 which the receptacle maybe slid preparatory to tilting the same to change the disposition of thepockets, and a nozzle adapted to discharge fuel into said pockets.

2. A. burner of the character described, comprising a casing providedwith a bottom opening, the casing being open at the top, the casingbeing also provided with an upstanding collar surrounding said opening,a sleeve adapted to fit within said collar, a fuel supply pipe extendingupwardly through the sleeve, nozzles connected to the upper endof saidpipe, the nozzles beingv supported'on the upper end of said sleeve andhaving their tips pointing downwardly toward the bottom of the casing,and receptacles in the bottom of the casing underneath the nozzle tips.

8. A crude oil'burner, comprising a casing provided in its bottom withan air inlet opening and a collar surrounding said opening, a sleeveadapted to fit in said opening, a downwardly facing spreader supportedby said sleeve, an oil receptacle in said casing, a fuel supply pipe,and anozzle secured to said pipe and adapted to discharge into saidreceptacle, said nozzle being supported on the upper edge of saidsleeve.

4. A crude oil burner, embodying a casing adapted to rest on the grateof a stove and arovided with an air inlet 0 enin throu 'h V s e H and anozzle adapted to dis- I provided with a plurality of oil receivingpockets or troughs, the casing being provided in its bottom with lugsagainst which the receptacle is adapted to be pushed preparatory totilting the same to change the disposition of the oil receiving troughs,and partitions mounted in the casing and extending upwardly from thebottom thereof between said lugs and the adjoining walls FREDERICK l).STALFORD.
